    Abstract: A method of forming a resist pattern in a semiconductor device layer includes forming a buffer layer on a semiconductor device layer and forming a resist layer on the buffer layer. A decomposing agent is released into a portion of the buffer layer by a portion of the resist layer whereupon the portion of the buffer layer and the portion of the resist layer are removed to form a process window substantially free of resist residue that can be subsequently exploited for etching of the semiconductor device layer.

    Abstract: An ESD-resistant photomask and method of preventing mask ESD damage is disclosed. The ESD-resistant photomask includes a mask substrate, a pattern-forming material provided on the substrate, a circuit pattern defined by exposure regions etched in the pattern-forming material, and positive or negative ions implanted into the mask substrate throughout ion implantation regions. The ions in the ion implantation regions dissipate electrostatic charges on the mask, thus preventing the buildup of electrostatic charges which could otherwise attract image-distorting particles to the mask or damage the mask.

    Abstract: An integrated circuit in which measurement of the alignment between subsequent layers has less susceptibility to stress induced shift. A first layer of the structure has a first overlay mark. A second and/or a third layer are formed in the alignment structure and on the first layer. Portions of the second and/or third layer are selectively removed from regions in and around the first overlay mark. A second overlay mark is formed and aligned to the first overlay mark. The alignment between the second overlay mark and first overlay mark may be measured with an attenuated error due to reflection and refraction or due to an edge profile shift of the first overlay mark.

    Abstract: A method of performing immersion lithography on a semiconductor substrate includes providing a layer of resist onto a surface of the semiconductor substrate and exposing the resist layer using an immersion lithography exposure system. The immersion lithography exposure system utilizes a fluid during exposure and may be capable of removing some, but not all, of the fluid after exposure. After exposure, a treatment process is used to remove the remaining portion of fluid from the resist layer. After treatment, a post-exposure bake and a development step are used.
